<p>Systems, methods, and miniature instruments (e.g., 12, 30, 40, 50, and 102) are disclosed for minimally invasive surgical procedures. A miniature surgical instrument can be inserted directly into a body cavity (16) through a cannula (10, 118) in a way that a surgeon can insert his or her hand into the cavity (16) through a separate minimal incision and use the miniature instruments. A miniature surgical system can include: a cannula (10, 118) having a hollow body configured to receive a miniature surgical instrument (102) and a tether (13, 104) connected to the instrument; and a plunger (108) sized to engage a proximal end of the body and including a conduit (106) therethrough for receiving the tether. The system can also include the tether and the instrument. During use, the instruments can be quickly and safely removed from the body cavity to enable the surgeon to use his or her fingers, e.g., to manipulate tissue.</p> |
